The claim is that smokers have a mean cotinine level greater than the level of 2.84 ng/mL found for nonsmokers. (Cotinine is used as a biomarker for exposure to nicotine.) The sample size is n = 920 and the test statistic is t= 56.224. Use technology to find the P-value. Based on the result, what is the final conclusion? Use a significance level of 0.05.

Diagnostic Tests: Total Calcium U has been treated for tetany (severe muscle spasms). This condition is associated with an average total calcium level below 6 mg/dL (Reference: A Manual of Laboratory and Diagnostic Tests by F. Fischbach). Recently, the patient's total calcium tests gave the following readings (in mg/dL): ver the past 9.3 8.8 10.1 8.9 9.4 9.8 10.0 9.9 11.2 12.1 ) Use a calculator to verify that = 9.95 and s ) Find a 99.9% confidence interval for the population mean of total calcium in this patient's blood. L) Interpretation Based on your results in part (b), does it seem that this patient still has a calcium deficiency? Explain. 1.02.

The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. The measurements are in tons per year, expressed as CO2 equivalents. Use a 0.025 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions. Based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions? A. Determine the test statistic. F= (Round to two decimal places as needed.) B. Identify the P-value. P-value= (Round to two decimal places as needed.)
